Group 4D Lithium Iron Phosphate Deep Cycle Battery, 36V 105Ah, ABYC Certified

WEST MARINE Group 4D Lithium Iron Phosphate Deep Cycle Battery, 36V 105Ah, ABYC Certified

Ultimate power for all-day performance. The WEST MARINE Group 4D Lithium Iron Phosphate Deep Cycle Battery in 36V 105Ah is engineered for serious boaters and tournament anglers who demand maximum runtime, peak trolling motor efficiency, and the reserve capacity to handle anything the water throws at them. With 105Ah of capacity at 36 volts, this deep-cycle battery is for anglers who fish full days without compromise, captains running multiple high-demand systems simultaneously, and anyone who refuses to let battery limitations dictate their time on the water.

Built on chemically stable, resilient LiFePO4 chemistry, the advanced battery management system protects against overcharge and overdischarge while maintaining an IP65 protection rating for the harshest saltwater and freshwater marine environments. With exceptional high energy density and power output, this Group 4D lithium battery delivers up to 10 times the lifespan of traditional lead-acid alternatives, translating to years of dependable service and dramatic cost savings that make the investment pay for itself. The lightweight design won't compromise your vessel's performance or fuel efficiency the way heavier lead-acid batteries do, keeping your boat responsive and economical whether you're running in shallow water, on open flats, or in extended offshore applications.

Deep discharge capability means you can safely access the full 105Ah capacity without worrying about cell damage or degradation, giving you genuine reserve power that carries you through entire fishing seasons and tournament schedules. Stable voltage output keeps your high-performance trolling motor spinning at peak efficiency, your marine electronics operating reliably, and your accessories delivering consistent power throughout every charge cycle.

Fast-charging efficiency minimizes downtime between outings, while zero maintenance requirements and eco-friendly LiFePO4 chemistry eliminate the sulfation and corrosion that plague conventional marine batteries. This is 36-volt deep cycle power at its finest: maximum amp-hour capacity, superior trolling motor efficiency, and the reliability that separates serious boaters from the rest.

This battery is ABYC certified, giving boat owners and marine professionals confidence that it meets established safety standards for use in recreational boats and marine electrical systems.

What is ABYC?

The American Boat & Yacht Council (ABYC) is a non-profit, member organization that develops voluntary global safety standards for the design, construction, maintenance, and repair of recreational boats. ABYC also provides standards-based technical education and training to help marine professionals build skills, stay current, and advance safety across the boating industry.
